Analyzing National Geographic as a Case Study for Identifying and Utilizing Narrative Strategies in Environmental Communication

Creator:: Chang, Kei Lin N.
Abstract:: National Geographic’s June 2018 magazine titled “Planet or Plastic?” drew attention to a growing problem throughout the world: ocean plastic. The eight plastic-related articles in the magazine are an example of science communication as a critical method of not only disseminating information but also raising awareness of the marine debris...

An Analysis of Nutrient Depletion in Douglas-fir Forests of the Oregon Coast Range

Creator:: Siah, Kaveh G.
Abstract:: Nutrient limitation constrains tree growth in many managed forests. Nitrogen (N) is the most common limiting nutrient, but high N supply can shift limitation to other nutrients, particularly phosphorus (P) and the base cations calcium (Ca), magnesium (Mg), and potassium (K). As different soil minerals have different capacities to supply...

Explorations Into Who is Doing Freshwater Science and How We are Altering Waterscapes

Creator:: Abernethy, Erin F.
Abstract:: The United States of America and the world are faced with three massive intertwining challenges at this time: COVID-19, racial inequity, and climate change. As a species, humans must come together and collectively address these challenges to preserve our humanity and make our world a more just and livable place...

Beyond Data and Learning Outcomes: Understanding the Personal and Social Dimensions of Citizen Science Volunteer Engagement

Creator:: Harwell, Todd A.
Abstract:: Citizen science is a term broadly used to describe activities that typically involve the public in the process, methods, and standards of scientific research with the aim of advancing scientific knowledge or application. Engagement in citizen science for project and program volunteers is influenced by much more than an individual’s...

Comparing Chemical Kinetic Model Reduction Techniques Using pyMARS

Creator:: Mestas, Phillip O., III
Abstract:: Accurately modeling the chemistry of conventional and alternative liquid transportation fuels in combustion technology is vital to predicting important quantities such as the burning rate, heat release, and pollutant emissions. However, incorporating detailed chemical kinetic models into reactive-ﬂow simulations poses a signiﬁcant challenge due to the associated high computational expense...

The Evolution of Software Entropy in Open Source projects: An Empirical Study

Creator:: Mannan, Umme Ayda
Abstract:: Software entropy impacts the overall quality of software systems. High entropy hinders developers from understanding the purpose of a piece of code and can cause developers to make sub-optimal changes and introduce bugs. Researchers have used entropy scores to measure the naturalness of code. However, thus far, no one has...

Reducing Biogeochemical Models with an Automated Reduction Method

Creator:: Klee, Emily
Abstract:: Modeling elementary chemical reactions in ocean ﬂuid dynamics simulations requires signiﬁcant computing resources, which can be diminished with model reduction techniques. Submesoscale ocean turbulence and biogeochemical reactions in the ocean occur on approximately the same time scale, 105 seconds. This similarity in time scales indicates a strong coupling between these...

Social Context Affects Response to an Acute Stressor in Captive Red Crossbills, Loxia curvirostra

Creator:: Tsuchihashi, Natsumi
Abstract:: Sociality relies upon mechanisms that permit group living through a balance of costs and benefits. However, it is not fully known how specific social contexts influence behavioral and physiological outcomes, and more broadly, how responses to social situations contribute to social organization. A recent experiment investigating the relationship between social...

On the Manifestation of Deformation and Evolution of Two Cenozoic Orogens

Creator:: Lamont, Ellen A.
Abstract:: The word orogenesis is derived from the Greek words oros meaning mountains and genesis meaning creation and refers to the study of the complex processes involved in the growth and evolution of mountain ranges (orogens). Orogens develop where crustal deformation builds topography and forms landscapes. This dissertation explores the role...

Temporal Variation in the Prey Resource Portfolio of Juvenile Salmonids During Freshwater Rearing

Creator:: Brady, Megan E.
Abstract:: Freshwater rearing is a critical period in the life cycle of anadromous salmonids, known to produce carry-over effects mediating long-term growth and survival. Freshwater growth is primarily determined by food availability and temperature. While many species of salmon rear in freshwater for a full year or longer, most trophic ecology...
